The parasitoidEphedrus cerasicola Stary oviposited in the 4 nymphal instars and in newly moulted apterous adults ofMyzus persicae (Sulzer). Development and reproduction of unparasitized and parasitized aphids at 21°C were compared. Unparasitized aphids developed to adults in 6.5 days and started to reproduce after 7 days. Longevity varied between 7 and 42 days. Net reproductive rate (R0) was 40.7.In contrast to older nymphs, aphids parasitized in the 1 st instar almost never reached the adult… 

Parasitization of Commercially Available Parasitoid Species Against the Lettuce Aphid, Nasonovia ribisnigri (Hemiptera: Aphididae)

It is concluded that A. abdominalis has the potential to be used against N. ribisnigri in inoculative biocontrol programs as compared with the other parasitoid species based on successful parasitization.

Host factors influencing the parasitism by Nesolynx thymus (Girault) (Hymenoptera: Eulophidae) on housefly, Musca domestica L.

The information on host factors generated will help to enhance the mass multiplication of parasitoid for the release of which would aid to bring down the M. domestica population in poultry and dairy units.

Fecundity and intrinsic rate of increase of the aphid parasitoid Ephedrus cerasicola Starý (Hym., Aphidiidae)

Species within the genus Ephedrus seem to have a very high fecundity compared with other genera of Aphidiidae.

Reproductive performance of Nesolynx thymus (Hymenoptera: Eulophidae) as influenced by host (Musca domestica) size

The parameters female and total progeny production per female, sex ratio, longevity, body length and wing span of males, females, head width of male, and abdomen length of female increased significantly with host size, and no impact of host size was observed on performance of first generation adults.

EFFECTS OF HOST AGE, FEMALE PARASITOID AGE, AND HOST PLANT ON PARASITISM OF CERATOGRAMMA ETIENNEI (HYMENOPTERA: TRICHOGRAMMATIDAE)

Abstract Parasitism of Diaprepes abbreviatus (L.) eggs by Ceratogramma etiennei Delvare as influenced by host age, age of the female parasitoid, and host plant preference was evaluated under

Host stage preference, juvenile mortality and functional response of Trioxys pallidus (Hymenoptera: Braconidae, Aphidiinae)

Host stage preference, juvenile mortality and functional response of the walnutaphid parasitoid wasp, Trioxys pallidus were studied in laboratory constant conditions.

Morphometric indicators for quality assessment in the aphid parasitoid, Lysiphlebus fabarum (Braconidae: Aphidiinae)

The results suggest that head width is a suitable morphometric for monitoring quality control in mass-reared cultures of this wasp.

Host selection behaviour of aphid parasitoids (Aphidiidae: Hymenoptera)

Three aspects of host preference behaviour, namely host recognition, host acceptance and host suitability have been discussed in this paper, which suggest that the learning ability provides the parasitoid with behavioural plasticity to adapt its responses to suit prevailing foraging opportunities.

Intrinsic rate of increase of Lysiphlebus testaceipes Cresson (Hym.; Braconidae), a parasitoid of Aphis gossypii Glover (Hom., Aphididae) at different temperatures

Longevity, reproduction, development, and intrinsic rate of increase of L. testaceipes were determined in the laboratory at two different temperatures with cotton aphids as host.

A comparison of life history traits of sexual and asexual strains of the parasitoid wasp, Lysiphlebus fabarum (Braconidae: Aphidiinae)

Biological characteristics of sexual and asexual strains of the parasitoid wasp, Lysiphlebus fabarum (Marshall) (Hymenoptera: Braconidae) are examined in this study.

Oviposition behaviour ofEphedrus cerasicola [Hym.: Aphidiidae] parasitizing different instars of its aphid host

The parasitoidEphedrus cerasicola Starý oviposited in all 4 nymphal instars and in newly moulted adults ofMyzus persicae (Sulzer). The different host categories were offered with no choice. The

Effect of host age at parasitization by Aphidius sonchi on the development, survival, and reproduction of the sowthistle aphid, Hyperomyzus lactucae

The numbers of young produced by parasitized aphids increased rapidly as the age of the hosts at initial parasitization increased, and aphids parasitized 3 days after the final moult or later showed similar potential to contribute to future population increase.

Laboratory Studies on the Rearing of Aphidius smithi (Hymenoptera: Braconidae) and Its Parasitism of Acyrthosiphon pisum (Homoptera: Aphididae)

In 4-hr parasitization periods with 40 Acyrthosiphon pisum (Harris) on Vicia faba leaves, Parasitization by Aphidius smithi was highest (82% average) with first-instar hosts, and declined to 0 with postreproductive aphids, and such differences in percent parasitized were not found in mixed groups of various instars.

THE EFFECT OF PARASITISM BY APHIDIUS SMITHI (HYMENOPTERA: APHIDIIDAE) ON REPRODUCTION AND POPULATION GROWTH OF THE PEA APHID (HOMOPTERA: APHIDIDAE)

Equations are given for the relationship between the mean total fecundity, the intrinsic rate of increase, and the doubling time of apterous and alate viviparous pea aphid and the aphid age at the beginning of parasitism.

Development, adult size and fecundity of Aphidius sonchi reared in two instars of its aphid host, Hyperomyzus lactucae

Development, adult size and fecundity of the aphid parasite, Aphidius sonchi Marshall, which began their development in the first and third instar nymphs of Hyperomyzus lactucae (L.), were studied in the laboratory.

Oviposition preferences of a hymenopterous parasite for certain instars of its aphid host

When the seven available instars and morphs of the aphid were exposed together to oviposition by its hymenopterous parasite, the numbers of eggs laid were highest in the nymphal instars, particularly in third instar hosts.

Aphidius rhopalosiphi produced 212 offspring on average but in one case 509 deposited eggs were found, indicating a certain degree of host discrimination.

Simple Estimation of Intrinsic Increase Rates for Aphids and Tetranychid Mites

The method has been shown to be equally applicable to tetranychid mites, by reference to published data, and suggested that a reasonably accurate estimate of generation time is provided by the value 4d/3.

EFFECTS OF CROWDING ON CLONAL CULTURES OF MYZUS PERSICAE (SULZ.)

Nymph production of the green peach aphid Myzus persicae decreased significantly under crowded conditions in leaf cages and on whole plants and mean daily nymph production was also slightly decreased.
